Really Mohela? My entire monthly income? How is that IDR?

Got this notice from Mohela today, starting 9/16/24 my payments will be $367.86 a month for four months, then it jumps to $2895.47…. The September payment is $100 more than it was, and the payments starting 1/16/25 is more than I bring home a month. The last I looked I was 15 months away from PSLF, even though I’ll hit my 10 years of qualifying employment in August.

Recalculating payments isn’t going to be fun either, since my spouse is self employed as of last October, so our income has changed but I don’t know by how much.
